Chris,
I have not worked on such a problem but I do have a GPR-90. As far as I
have seen the drift in it is normal for a thing of its nature..(LC- tunable
local oscillator with non-oven temperature control but high quality
components) Tell me how much yours drifts and on what band.
I will, of course, be interested in what you discover. Background reading
on this would include those articles of the 50's and 60's about tube type
VFO's in QST.
